The gas inside a cylinder expands against a constant external pressure of 0.953 atm from a volume of 4.51 L to a volume of 14.50 L. In doing so, it turns a paddle immersed in 0.962 L of liquid toluene (C7H8). Calculate the temperature rise of the liquid, assuming no loss of heat to the surroundings or frictional losses in the mechanism. Take the density of liquid C7H8 to be 0.867 g cm-3 and its specific heat to be 1.69...
